How long do you have to wait put a fish in BiOrb tank?

The amount of time you need to wait before putting a fish in a BiOrb tank depends on the type of fish and the specific BiOrb tank model. Here are some general guidelines:

- Freshwater fish: For most freshwater fish, you should wait at least 24 hours after setting up the tank before adding fish. This allows the beneficial bacteria in the tank to establish and start to break down harmful chemicals such as ammonia and nitrite.

- Saltwater fish: For saltwater fish, you should wait at least 4 weeks after setting up the tank before adding fish. This gives the coral time to settle into its environment and begin to provide adequate levels of dissolved calcium and other elements needed by corals and salt water fish.

It's important to follow the instructions provided by the BiOrb manufacturer and to monitor the water quality carefully before and after adding fish to ensure a safe and healthy environment for your fish.
